To reduce the size of the installer of the 2017 Expansion Pack, we decided to release most of the race variants as a DLC, like in some of the past editions. This DLC contains all the Continental Tour (.HC to .2) variants, as well as most of the WorldTour variants, and the National and World Championships ones. We kept at least 2 variants of each World Tour race in the base download, with that being said. You can find the download link at the bottom of this post. Below, you can have a quick look over the full amount of World Tour and WC variants you will be able to enjoy by downloading both the EP and the Variants DLC, excluding the ones in the base game and the CT races included in the DB.
